Kernrechtsfrage
Whether the appeal against administrative detention still had an object after the appellant left Switzerland.
Extrahierter Entscheid
The appeal had become moot because the appellant had left Switzerland; the court took note of this and struck the case from the docket.
Extrahierte Begründung
A request for immediate release no longer had any practical purpose once the detainee was no longer in Switzerland, so there was no live controversy to decide.
